Usually sendmail seems to work "out of the box" for me. Not this time. I just did a major upgrade from Ubuntu 7.whatever to Slackware 12.1 on my server. I run 12.1 on my desktop with mutt, procmail, fetchmail, and sendmail, so I figured it wouldn't be all that difficult to get my server working. Well...
I'm trying to set it up so that mail sent on my website (using php) will be sent to my email address. Currently sendmail works from one local user to another, but not "externally". Since this is the only use for sendmail on my server, I set the user "apache" as the only user in the trusted-users file in /etc/mail.
My iptables script is set to:
$IPT -A OUTPUT -p TCP -o eth0 --dport 25 -m state --state NEW -j ACCEPT
I copied the sendmail.cf and submit.cf files from my desktop to my server hoping they would clear up any errors.
The really strange thing is that I do not get any error messages in maillog, messages, httpd's error log, root or user mailboxes.
Does anyone have any idea as to what I need to check next?
